Answer:

20 men will paint the same wall in 3/4 hours.

Step-by-step explanation:

Given information is:

5 men paint a wall in 3 hours

Let x be the number of men

It is also mentioned that the rate will be same with x men. So we have to put both the rates/proportions equivalent to find the number of men.

So,

men * hours = men*hours\\5*3 = x*\frac{3}{4}\\15 = \frac{3}{4}x\\x = \frac{4}{3} * 15\\x = 20

Hence,

20 men will paint the same wall in 3/4 hours.

an air conditioning system can circulate 360, cubic feet of air per minute. how many cubic yards of air can it circulate per min
ahrayia [7]

Alright, lets get started.

3 feet = 1 yard

If we cube both sides of the equation, we will get the conversion into cubic yards

So,

3*3*3 cubic feet = 1 * 1*1 cubic yards

27 cubic feet = 1 cubic yards

So, 1 cubic feet = \frac{1}{27} cubic yards

So, 360 cubic feet = 360 *\frac{1}{27} cubic yards

So, 360 cubic feet = 13.33 cubic yards

13.33 cubic yards of air can it circulate per minute. : Answer

Hope it will help :)
